Answer:
the number is 8 andequation is 3x-5=19
Answer:
B. 152 + 7
Step-by-step explanation:
(8x + 16) + (7x - 9)
8x + 16 + 7x - 9
15x + 16 - 9
15x + 7
None of these options have this answer, so we see A and B:
A. x + 7
B. 152 + 7
It can't be A because we have 15x and A is x + 7
By process of elimination we have B. 152 + 7
x = 10 and 2/15
If there is a porpotional relationship then it there will be a pattern like, 7, 14, 21 etc. You can tell because the line will go straight in a perfect line and won't go at a different andle from the rest of the line.
